Summary page in Management Reports in EPM Planning when selected multiple entities

There is a need to display the summary of the entities selected based on the prompt.

Example:

Let's say there are 5 entities: 01, 02, 03, 04, and 05, and the P&L accounts are as below for each entity:

Net revenue: $100

Revenue: $200

Expense: $150

Case 1: When the report is run for entity 01, it should display P&L accounts for entity 01 alone.

Output:

Net revenue: $100

Revenue: $200

Expense: $150

Case 2: When the report is run for more than one entity, i.e., 01, 03, and 04, it should display the sum of P&L accounts for all the entities and not the individual entity.

Output:

Net revenue: $300

Revenue: $600

Expense: $450

Please advise.
